Engineering for farms

Tunnel ventilation

For hot weather. Air enters through tunnel inlets with cooling pads at one end of the house, travels along its full length and leaves through exhaust fans in the opposite end wall. The side-wall inlets are fully closed; only the tunnel shutters in the cooling-pad zone are open. Air speed and inlet cooling reduce heat stress on the birds.

Minimum ventilation

For the cold season and young birds. Fresh air enters only through the side-wall inlets, which run the whole length of the house on both long walls, including along the cooling pads. In this period the cooling pads do not work and the tunnel shutters are closed. The inlets direct the air under the ceiling; it mixes with warm air at the top of the house and is exhausted through chimneys. The aim is to remove moisture and gases without chilling the birds.

Pens and slatted floors, feeding, gravity manure removal, ventilation, cooling, heating and climate control. The supply and exhaust scheme is chosen for each section type and building design.

For cattle we work with air: ventilation, air exchange, cooling and climate control. Fan placement and air exchange are calculated for the design of the barn.
